Here is a page of great talks from “TED” (Technology, Entertainment, Design. www.ted.com)
Juan Enriquez offers a glimpse of some ground-breaking research to explore the potential of bioenergy. Our current energy sources — coal, oil, gas — are ultimately derived from ancient plants — they’re “concentrated sunlight.” He asks, Can we learn from that process and accelerate it? Can we get to the point where we grow our own energy as efficiently as we grow wheat? (Less than a month after this talk, his company announced a process to do just that.)

“I don’t think we’re going to make it,” John Doerr proclaims, in an emotional talk about climate change and investment. Spurred on by his daughter, who demanded he fix the mess the world is heading for, he and his partners at Kleiner Perkins Caufield & Byers embarked on a greentech world tour — surveying the state of the art, from the ethanol revolution in Brazil to Wal-mart’s (!) eco-concept store in Bentonville, Arkansas. KPCB is investing $200 million in green technologies to save the planet and make a profit to boot. But, Doerr fears, it may not be enough.

Environmental scientist David Keith talks about a cheap, effective, shocking solution to climate change: What if we injected a huge cloud of ash into the atmosphere, to deflect sunlight and heat? As an emergency measure to slow a melting ice cap, it could work. Keith discusses why it’s a good idea, why it’s a terrible one — and who, despite the cost, might be tempted to use it.

– Architect and designer William McDonough asks what our buildings and products would look like if designers took into account “All children, all species, for all time.” A tireless proponent of absolute sustainability (with a deadpan sense of humor), he explains his philosophy of “cradle to cradle” design, which bridge the needs of ecology and economics. He also shares some of his most inspiring work, including the world’s largest green roof (at the Ford plant in Dearborn, Michigan), and the entire sustainable cities he’s designing in China.

Accepting his 2007 TED Prize, Bill Clinton says he’s trying to build a better world to hand to his daughter. Unequal, unstable and unsustainable, our world must correct its course, and private citizens (“like me”) can be powerful forces for change. His Clinton Foundation, fresh from its success negotiating down pharmaceutical prices in the developing world, is now running a pilot health care system in Rwanda, based on the work of Dr. Paul Farmer in Haiti. In 18 months, it has shown potential as a model for the entire developing world. Clinton’s TED wish: Help him build this system in Rwanda, to bring world-class health care to a people who have overcome deadly hatred to rebuild their nation.
